feat(core): add @choojs/core — ESM port of choo with consolidated nano* internals

Same public API as choo 7.1.0 (use/route/start/mount/toString/emit; choo() callable with or without new, Choo exported). nanobus, nanorouter+wayfarer, nanolru+component cache, nanoraf, nanohref, nanotiming, document-ready and scroll-to-anchor are ported into lib/ with per-file attribution; nanoquery is replaced by URLSearchParams. The v7 node test suite is ported from tape to node:test and passes unchanged in behavior.
